The lax sealing of the oil seal is the main factor causing the oil spill.When the shaft wears out to form a groove, and even if a new oil seal is used, it still cannot be sealed, it is due to the decrease in the contact pressure between the oil seal lip and the shaft, resulting in the interference between the diameter of the oil seal lip and the shaft diameter after installation is too small.Taking the S195 diesel engine crankshaft oil seal as an example, the main reasons for the lax sealing are analyzed.:

The manufacturing quality of oil seals is poor;
The quality of the shaft or bearing is poor;
Improper use and maintenance;
